FAQ: How To Lay Ceramic Tile On Concrete?

Can you put ceramic tile directly on concrete?

A: It’s perfectly acceptable to put tile directly on concrete — with a couple of caveats. First, it is important to determine if there is moisture coming up from the slab. Those products should help prevent any cracks in the slab from damaging the newly installed tile.

How do you prepare a concrete floor for ceramic tile?

Start by sweeping your concrete floor to get rid of all dust and debris. Then clean with a wet mop of plain water. Use a few tablespoons of a degreasing cleaner in warm water and scrub the concrete with a scrub brush. Finally, rinse thoroughly.

Do I need underlayment for tile on concrete?

Although you don’t need to install an underlayment between the concrete and the tile, you need to prepare the surface before placing the tile. After all, cracks and uneven areas in the concrete can cause damage to the tile above, and uncontrolled moisture in the concrete can destroy the mortar and loosen the tiles.

What type of thinset do you use for ceramic tile on concrete?

Modified thinset is the product of choice for most tile installations because of its increased strength and bonding with minimal shrinkage, which means a reduced chance of cracks forming in the tile. WarmlyYours Radiant Heating recommends modified thinset mortar for nearly all tile and stone installations.

Do you need a moisture barrier under ceramic tile?

Ceramic Tile and Water



But if moisture seeps through the grout in the joints between tiles, it can degrade the thin-set adhesive used to secure the tile and cause the floor to fail. The grout used to fill the joints between tiles is not naturally waterproof, so it needs to be sealed to prevent moisture infiltration.

What goes under ceramic tile?

Oriented strand board (OSB) and exterior-grade plywood will work if first covered with a latex-modified mortar and a tiling backer board. Install a cement-based backer board following the manufacturer’s instructions. This provides a solid surface under the tile that prevents flexing that could lead to cracking.

How do I tile over concrete?

What is the difference between mortar and thinset?

Does tile need underlayment?

Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.
